Effect of AIRVO Heated Humidification in Bronchiectasis

2019-09-30 07:07:00 | BioPortfolio


The aim of the study is to investigate whether long-term heated humidification therapy (AIRVO) administrated for 1 year over-night on top of standard therapy can reduce the number of exacerbations in adults with non-cystic fibrosis bronchiectasis.


Bronchiectasis is a chronic condition characterized by an abnormal widened airways, mucus retention, cough, daily sputum, and frequent respiratory infections. The management of bronchiectasis includes prevention of exacerbations and lung infections along with airway clearance techniques.

Mucus composition and hydration are crucial to allow mucus transport along airways during respiratory physiotherapy.

Previous studies showed that long term humidification therapy increased airway clearance (Hasani et al. 2008) and reduced the number of exacerbations in patients with both bronchiectasis and Chronic Obstructive Pulmonary Disease (COPD) (Rea et al. 2010). myAIRVO2 system can deliver high-flow warm and humidified gases through a nasal cannula.

The aim of the present study to assess the effect of long-term use over-night of myAIRVO2 warm humidification in adults with bronchiectasis who experience at least 3 exacerbations/year still with optimized clinical and respiratory therapies.

In addition to their usual therapy, the treatment group will receive a myAIRVO2 humidifier at home deliver every day for one year over-night.

The gas flow setting will be set between 20 and 30 l/min based on patient preference, temperature will be 37°C and, for patients already in long-term oxygen therapy, FiO2 will be regulated according to patient's prescription.

The control group will continue to receive standard therapy for bronchiectasis according to international guidelines.

Patients will be screened during outpatient visits and, if they meet study criteria, they will be enrolled in the study. Once enrolled in the study, patients will be followed up every 3 months with 4 consecutive outpatient visits. The following endpoints will be assessed: exacerbations frequency, quality of life, pulmonary function and, for patients enrolled in the treatment group, myAIRVO2 use, and comfort.

Statistical analysis will be performed by Prof. Giovanni Sotgiu (University of Sassari - Italy).

Failure or imperfection of vision at night or in dim light, with good vision only on bright days. (Dorland, 27th ed)

A species in the family AOTIDAE, inhabiting the forested regions of Central and South America (from Panama to the Amazon). Vocalizations occur primarily at night when they are active, thus they are also known as Northern night monkeys.

Institutional night care of patients.

Persistent abnormal dilatation of the bronchi.

A rehabilitation therapy for removal of copious mucus secretion from the lung of patients with diseases such as CHRONIC BRONCHITIS; BRONCHIECTASIS; PULMONARY ABSCESS; or CYSTIC FIBROSIS. The patient's head is placed in a downward incline (so the TRACHEA is inferior to the affected area) for 15- to 20-minute sessions.
